they may not be right though...sorry

My post is at the top

Anonymous's first answer is correct. However, the second is wrong.
8a4+82a=156
6a = 156 + 4  8
6a = 152
a = ? 
thanks

What math are you in?

You mean what math class? I'm in geometry.

so then 6a = 25.33333333repeating? something or other?

1.whats the value for h in 12h+9=85?
12h=76
h=76/12
h=6.333
2.whats the value of m in 6m squared + 5 = 128?
6m^2=123
6m=square root of 123
6m=11.091
m=1.85
3.what's the value of a in
8a4+82a=156
combine terms so 6a+4=156
6a=152
a=25.333
